​At one point, Kristy Mandigo was seeing 15 different specialists. Then she met David Millett, M.D., Ph.D.

Now she's just seeing one.

Born with right sided hemiplegia and spastic cerebral palsy, Kristy Mandigo was never expected to walk normal, talk normal or graduate from elementary school. She didn’t learn how to read (conventionally) until she was in junior high. She had a great memory, which hid many of her challenges. At the age of 16 she developed seizure disorder. The first seizure was so intense, she could only drink from a sippy cup for days. Her seizures thereafter seemed to intensify with different side-affects.

Today, Kristy is a 34-year-old MBA with an engineering degree who works at Raytheon. She is happily married and is the mother of two healthy young boys – improbable feats Kristy shrugs off: The exceptional is nothing new to her.

The high-powered media executive suffered a brain tumor in 2009 that she thought would be the worst thing to happen to her. While on a business trip to Cleveland, she woke up alone in a conference room in a pool of blood. She thinks she hit her head on a marble table, but doesn’t know how. A medical team at the Cleveland Clinic put 18 stitches in her head and assessed her before she returned to Orange County.

“They said, ‘You need to go right to the Hoag Neurosciences Institute and see a brain doctor,’” Osborn says.

​Samantha Estock was just 12-years-old when the seizures began. Sometimes they’d come in rapid succession – as many as three per minute. Sometimes she’d get as many as 200 seizures in one day.

The seizures sapped her energy, and dramatically altered her life but Samantha said they also made her a more compassionate person. The 23-year-old writer noted a kindred sense of compassion in David Millett, M.D., Ph.D., Epilepsy Program Director at Hoag Neurosciences Institute.

“He takes into consideration how you feel. If you’ve already taken a million medications, and it is hard to try the same medications again, he takes that into consideration and really listens,” Samantha said. “He’s the best doctor I’ve ever had.”
